The invention relates to a device and a method for adjusting the spatial orientation of a self-rotation axis of a microsatellite. According to the adjusting device, a pair of opposite connecting lugs are arranged at one end of the satellite body, two parallel connecting shafts are connected between the two connecting lugs in a penetrating mode, and each connecting shaft is connected with an end expander. The two end dilators are arranged side by side, have the same mass and the same center-of-mass position, and are symmetrically distributed by taking the central axis of the satellite body as the symmetry axis; deflection driving mechanisms are mounted in the end part dilators and are used for driving the end part dilators to swing outwards around connecting shafts connected with the end part dilators in a penetrating manner, so that the two end part dilators are synchronously opened and closed. On the basis of the axial overturning effect generated by the Gannikov principle, adjustment and change of the direction of the rotating shaft of the microsatellite are achieved through the interaxial transformation technology in an electromechanical combination mode. The invention provides a new technical support for changing and adjusting the rotating shafts of microsatellites adopting a spinning attitude stabilization mode in space or objects of the type in a weightless environment.
本发明涉及一种微小卫星自旋转轴的空间指向调节装置及调节方法。所述调节装置是在卫星本体的一端设有一对儿相向而立的连接耳,在两个连接耳之间穿接两根平行设置的连接轴,在每个连接轴上接有一个端部扩张器;两个端部扩张器并排设置,其质量相同,质心位置相同,并以卫星本体的中轴线为对称分布;在端部扩张器中安装有偏摆驱动机构,用于驱动端部扩张器绕各自穿接的连接轴向外侧摆动,以实现两端部扩张器的同步开合。本发明是基于贾尼别科夫原理所产生的轴向翻转效应,使用机电结合的方式,通过轴间变换技术,实现微小卫星转轴指向的调整和改变。本发明为空间采用自旋姿态稳定方式的微小卫星或失重环境下的此类物体的转轴改变和调整提供了一种新的技术支持。
